b3cec96a7c Account for the VTT argument when making an implicit copy constructor for 
a class with virtual bases.  Just a patch until Sema starts (correctly) doing
most of this analysis.

Fixes PR 6622.

6a0227df49 Fix a bug which triggered the assertion I added yesterday. Basically, when we initialize the vtable pointer for a virtual base, and there was another path from the most derived class to another base with the same class type, we would use the wrong base.

c4df407604 Keep track of the actual storage specifier written on a variable or 
function declaration, since it may end up being changed (e.g.,
"extern" can become "static" if a prior declaration was static). Patch

c50c27cca8 the big refactoring bits of PR3782. 
This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

74eab715ae More improvements to setting the vtable pointer. We now no longer set the vtable pointer for non-virtual primary bases. We also do a pre-order traversal of the class hierarchy; this is necessary in order to get the right vbase offset offsets in base ctors/dtors.
